Mylnvention relates to IIllXlIlg apparatus,iand more particularly toapparatus for mix ng foodgmaterials forlive stock, but it *oth'erkin'ds5I I One object of my invention is to provide apparatus for effectivelymixing materials into'which' is"introduce'da liquid content such asmolasses,'for exampleJ i- 5 vide in combination with a mixingapparatus,-meansfor more effectively removing the mixed materialstherefrom.

A further object'of my invention is to providean improved means forcharging the materlals'to the mixing apparatus; Anotherjob'jectf ofmyinvention is to provide' means for moreefl'ectively circulatingmaterials during a mixing'operatlon and for 2'0 intermixing thematerials reproduce a thorough dissemination of the various ingredientsthrough the resulting-mixture.

Stillanother object of'my invention is to simplify and improve generallythe structure and operation of apparatus of the character referred to.-

The conveyer also passesthrough a charging chamber or material-receiving chamber or hopper13'th'at ismounted below the floor level and has communication with thehopper 7 A charging "ope'ning 14 is provided in thefioor and suchAnother object of my invention is to pro-1 opening maybe covered by aplatform or plate 15 when material'is not being dumped into the hopper13. a maybe employed in mixing materials of I through the casing 12.-The chain is driven -by the sprocket wheel 18 from a shaft 19 whichcarries a pulley 21 that may be driven from any suitable source of"power, the shaft 19- having driving connection through sprocket wheelsand a chain 22 with a'shaft 20- which carries thesprocket wheel 18.

It will be seen that when materials are introduced-- into the "chargingchamber 13,

they will be caught by the moving vanes of the conveyer and carriedthrough the conduit 8. The materials are discharged at the-upper end ofthe conduit 8 in the form of a spray and fall or sink into the hopper 7.

The materials are'charged into the chamber '13, until a sufficientquantity has accumu-' lated in the mixing. chamber 6 or until such 7 a.I I chamberisnearlyfull. One form ofapparatus by which my in- 1Continued travel of theconveyer will circulate the materialrepeatedlythroughthe v conduit- 8 to effect thorough intermixing 30 a view,thereof partially inside elevation and thereof." If molasses or someother mixture has to be incorporated in the mixture, it

'may be introduced into the mixing chamber,

1 of the 'conduit to the hopper 7 it will be p v 1 broken upby" toothedrollers 25 whichare The apparatus includes a m-ixing chamber arranged-inrectangular formation in the hopper"? and; are driven from the shaft 19by belt drives-26 a'nd27 The toothed rollers serve to effectively mixthe various ingredients andare particularly useful if molasses orsomeother liquid is beingincorpo- 12.. A deflecting plate38 is providedinpivoted at 31 and carries a crank arm 32, while the trough 29 is looselymounted 011 the shaft which carries the sprocket 17 and has a crank-likeextension 33. The extension 33 is connected through toggle links 34: tothe trough 28.

Ordinarily, the troughs occupy the positions shown in Fig. 1, so thatthere will be no interference with circulation of the materials in themixing chamber.

After the materials have been tho'roughly mixed, the crank arm 32 isrocked in a counter-clockwise direction by meansof a hand lever 35 and alink 36, thus swinging the trough 28 upwardly and moving the trough 29in a clockwisedirection, to the positions shown indotted lines in Fig.1.

The movement of the trough 29 into position over theconduitS is causedbythe bottom of thechute 28 engaging the toggle links .34 during upwardmovement of such chute. A pin-37 is mounted in the side wall of thechute 28 to breakthe toggle and to retract the chute v29 when the chute28 is being swung to inoperativeor retracted po- ,end of the conduit 8laterally to the casing such casing, to direct the ;material toward theouter Wall thereof and to a position whereit will fall tothe'dischargespout 39 of ;the casing.

It, will be seen that the downwardly-moving run, ofthe conveyer chain 10is inclined and that the .vanes 11 thereof slope toward theouter wall oftheicasing :12. This ar- --rangement results in any liltitflriitl whichfalls upon the upper sides. of the descending vanes '11 being deflectedstill further laterallyztoward :the discharge spout 39.

Another advantage arising from directing ,the conveyerathrough; agenerally hori- Zontal path attheupper end of thelmixing chamber.residesinthe fact'that it enables the return run of the conveyerto lieoutsideLof the mixing chamber. If both verticalfrunsof theconveyer werelocated entirely the mixing chamber, it will .be seen that therewould.be,a tendency for a portion only of the materials to be circulatedby the6conveyer, leavingthe other portions thereof undisturbed.

The dischargespout is controlled by a valve 41 which is operated by ahandle .42. Whenithe handle 42 is raised, the upper edge of the valve 41is swung toward the conveverchain, thus permittingmaterial to fallthrough the spout 39 into sacks or other receptacles ,placedtherebeneath.

The hinged ;plate ,15 serves not .only as a platform, but asa cover ,forthe chamber 13. NVhen the chamber l3 isbeing charged,

-whichcarries-the sprocket 16, are secured po lygonally-shaped discs orplates 1-8 against which the lower ends of the arms 45 bear, the .weightof the platform 15 serving to hold such lower ends in engagement withthe discs ,48. As the shaft 47 rotates, the discs 4.8 will causeoscillation of the arms 45 about their pivots 4:6, thus vibrating theplatform 15 and effecting settling and compacting of the materials inthe bags being filled.

Certain of the vanes 11 carry wiping strips 11, as shown more clearly inFigs-4 and 5, to serve as scrapers and prevent accumulation of materialagainst the walls of the conduit 8. These strips may be of fiber boardorany other suitablematerial.

The apparatus above described is shown as mounted within a framework 50of angle bars and the like-that are suitably secured together to form aunitary structure with the workparts, so that the entire apparatus can.be shipped in assembled condition and conveniently installed at theplace of use.
